Token drop rates

Hunting gargoyles(awful) at Tir's rb area gave about 25 over 30 minutes, while tnn zombies(boss) gave 50 over 30 minutes. I guess cp's behind this correlation c:

That's a bit odd, generally over the course of 1 ingame day, roughly 16 minutes, I farm 10 tokens in a single kitchen dungeon. Then when I start another I get almost zero tokens on that run for a period of time, then all of a sudden it starts appearing again at some point. Maybe it's limited per chunk of time?

10 tokens per 10 minutes for SM?

Also, Zombies aren't boss to me... So Zombies won't work well unless I have CP reducing items for that. The only thing that is Boss and easily killable is kitchen dungeon ingredients unfortunately.
